AND userid = 2
ORDER BY dateline

Try changing it to IF(filesize > 0, 1, 0) ??

The column `thumbnail_filesize` doesn't exist in the table `attachment`.

Use PhpMyAdmin to verify the column exists, or DESCRIBE attachment; in SSH.

If this is a custom hack, I would forward this question to that author's thread.
